Geoplana apua is a species of land planarian belonging to the subfamily Geoplaninae.

[1] It is found in areas within the Atlantic Forest in the municipalities of Nova Iguaçu and Teresópolis, Brazil.

The dorsal side has a luminous orange band running down the middle, flanked on each side by a black stripe; the black stripe is bordered on the outside by a greenish-yellow stripe, which is bordered by a black band.

[2] Aside from its coloration, it is distinguished from other members of Geoplana by having two-layered musculature of the inner pharynx, a developed anteroventral region of the penis bulb, and a penis papilla with the dorsal insertion displaced anteriorly and very ventrally, as long as 18 times its diameter.

[2] The specific epithet, apua, is derived from a Tupi language word meaning "mound", in reference to the hills where type specimens were collected.
